A maternity bed incorporates a patient lying surface with pelvis, lumbar, and upper back regions, and left and right sides. The lying surface has two or more actuatable lifting elements arranged at the lying surface, and may incorporate four or six or more lifting elements. The lifting elements may include a left pelvis lifting element and a right pelvis lifting element at the pelvis region of the lying surface, a left lumbar lifting element and a right lumbar lifting element at the lumbar region of the lying surface, and a left upper back lifting element and a right upper back lifting element at the upper back region of the lying surface. At least one actuator may actuate the lifting elements to raise and lower various regions of a patient, such as to provide a turning function, and may be controlled by a user input device.
